Dear sudipj<div><br></div><div>I tried to add caps in gstreamer pipeline like </div><div>"gst-launch-1.0 videotestsrc ! Video/x-raw, format=BGRx ! Waylandsink".its working successfully. </div><div>Then i tried with a BGRA video like </div><div>"gst-launch-1.0 filesrc location=sample.bgra ! Video/raw, format=BGRA, width=352, height=288, framerate=25/1 ! Waylandsink"</div><div>I got a green line in display with errors like</div><div>(gst-launch-1.0:442):Gstreamer-CRITICAL **:gst_buffer_fill: assertion 'GST_IS_BUFFER(buffer)' failed caught SIGENV</div><div>#0 0Xb6c27380 in poll() from /lib/libc.so.6</div><div>#1 0xb6f414c0 in?? () </div><div>Spinning. Please run 'gdb gst-launch-1.0 442' to continue debugging </div><div><br></div><div>So i debugged it. That i attached with this mail. </div><div>Then i used another pipeline</div><div>"gst-launch-1.0 filesrc location=sample.bgra ! Videoparse width=352 height=288 format=8 ! Videoconvert ! Waylandsink ". </div><div>I got a freeze image on the display, video not playing and showing same error. </div><div>I think some buffer error behind it.
